posite faces adapted to form inner and outer wall surfaces, these' face portions being joined by cross Webs. The cross webs extend vertically `to form separated, vertically extending air spaces. The blocks are laid with mortar and this mortar is substantially more pervious to moisture than the blocks themselves. It is highly desirable `therefore that the mortar does not `extend. continuously between the outer and inner wall faces.

wasted but has adetrimental effect.

Since such blocks have spaced, narrow, `vertically extending meeting ends it is important thatr these ends be fully bonded by mortar. With usual square meeting faces it is dimcult to secure such a bond with the mortar filling the joint flush with the wall faces. Also, if pointing `is necessary to secure proper joints there is a tendency for mortar to push through the relativelyshallow joint and be wasted.

it is an object of the present invention to provide a new and improved building block.

It is a further object to provide a block provided with cross webs so formed as to prevent a continuous mortar joint between Vthe inner and outer block faces. v

It is an additional object to provide a'block with end faces formed to facilitate a full mortar joint and to minimize inward `flow of mortar in the joint. v

Itis also an object to provide a block which is simple in design and construction and adapted for commercial production and use.

Other and further objects will appear as the description proceeds.`

I have shown a preferred embodiment of my invention in the accompanying drawing in Which- Figure 1 is a plan view of a block;

Figure 2 is a vertical section taken on line 22 of Figure 1; and

Figure 3 is a plan view of a series ofblocks, partly broken away, showing the vertical mortar joints. y

In the drawing, the block is provided with the Excess mortar on the cross webs is not only.

wall face portions II and the cross webs I2` The Webs I2 have their upper portions formed with sloping faces I3 meeting in a line I4 substantially in the plane of the upper faces of the wall portions II. t

The ends I5 of therface portions II are shaped upon an outwardly inclined slope or bevel with a vertically extending chamfer or groove I6 formed therein.

In the use of the blocks they are, placed in a `wall in the position shown in Figure 2, with the pointed or gabled edges of the webs on the upper face ofthe blocks. In laying the blocks mortar is placed upon both the face portions II, but noneV on the cross Webs I2. If any mortar is accidentally placed upon the cross Webs, the gabled upper edges cause the mortar to drop off and prevent the formation of a continuous mortar joint from the outer to the inner wall face.

Mortar is placed upon the vertical end edges I5 of one block and as the two blocks are brought longitudinally together, due to theslope of these edges I5, the mortar is squeezed outwardly to form a full joint. This minimizes any necessity for pointing the vertical joints, but if any such pointing is necessary, the slope of the edges I5 is such as to compact and hold the mortar in the joint rather than to permit it to pass through and be partially wasted, as would be the case with end edges at right angles to the wall faces. The grooves I6 fill with mortar andincrease the effective bond between the mortar and the block besides forming locking keyways for the mortar when it is set. t e

My improved block, therefore, substantially eliminates the possibility of a continuous mortar joint between the inner andoutei` wall faces and also provides a more efficient end joint. Both features serve to cut down the labor expense of laying a wall of the blocks and also serve to minimize the amount of mortar required.

While I have shown one preferred embodiment of my invention, this is to be understood to be illustrative only as it is capable of modification to meet varying conditions and requirements and I contemplate such variationsas come within the spirit and scope of the appended claims.

I claim: t

1; In a building block construction, a unitary t block comprising spaced vertically extending wall portions and narrow spaced transverse webs between the Wall portions, the webs extending vertically and having upper portions substantially pointed in cross section and located within the contour of the block.

2. In a building block construction, a unitary block comprising spaced vertically extending wall portions and spaced transverse webs between the wall portions, the webs extending vertically for substantially the depth of the wall portions and the upper portion of the webs being gradually reduced in cross section to substantially a line in the plane of the upper faces of the wall portions.

3. In a building block construction, a unitary block comprising spaced vertically extending wall portions, means connecting the Wall portions, the ends of the wall portions being lsloped to provide vertical wall joints between adjacent blocks decreasing in width inwardly from the face of the blocks.

4. In a building block construction, a unitary block comprising spaced vertically extending wall portions, means connecting the wall portions, the ends of the wall portions being sloped to provide Vertical wall joints between adjacent blocks decreasing in width inwardly from the face of the blocks, and vertically extending grooves in the 10 ends of the wall portions.
